[Review]XFX nForce 790i Ultra
nForce 790i Ultra SLI feature: EPP 2.0
NVIDIA’s EPP 2.0 means Enhanced Performance Profiles 2.0, in other word that is DDR3 version of EPP. When EPP 2.0 memory (they call it SLI-ready) have been plugged in to 790i Ultra, BIOS will read SPD from memory, adjusting memory frequency timing and voltages. make it runs at the best rate.
790I Ultra SLI is the first NVIDIA mobo that supports DDR3 memory, so NV upgrade EPP to 2.0 to support DDR3 memory. It is not a simply port, EPP 1.0 only can auto-adjust timings but EPP2.0 can also link up with CPU frequency multiplier and voltage adjusting. With all these, the memory can boost more. All we need to do is open EPP 2.0 options in BIOS, and our Crucial Ballistix runs at DDR3 2000MHz 9-9-9, and voltage only at 1.9V.
EPP is first announced in 590SLI Intel Edition, after that 680i and 780i all supports EPP1.0. Because AMD have integrated memory controller in CPU so NVIDIA never launch any EPP product in AMD platform. That means when Intel unveils their new era CPU (Nehalem) also have memory controller integrated, EPP will be EOL.

Hi,
fist I would thank you for your great job!!!
but I have a question I hope you’ll answer me:
I’d like to buy this mobo with OCZ Flex II XLC 2 x 1 Go PC16000 and a E8500, is it a good choice to do a good overclock ?
Thanks
